ロセスを完了する。Conventional Structure and Problems Generally, an electrophotographic copying apparatus using an organic photoconductor photoconductor has an endless belt-like photoconductor 61 (hereinafter referred to as
A photoreceptor (referred to as a photoreceptor) is run by a photoreceptor driving drum 51a and a photoreceptor driven roll 51b, the photoreceptor 61 is charged by a charging charger 62, and the photoreceptor 61 is charged from a document table 64 by an exposure device 63 having an exposure lamp 53a and an optical fiber lens s3b. A light image is formed as an electrostatic latent image on the photoreceptor 61, and developed by the developing device 65 to become a visible image. Next, the copy paper 57 is fed from the copy paper strength center 56 by the paper feed roll 68, and the copy paper 67 is conveyed onto the toner image on the photoreceptor 51 by the transport roll pair 69 and the transfer guide 60, and the electrostatic The toner image is transferred onto the copy paper 67 by the transfer charger 61. As the photoreceptor 51 and the copy paper 67 further advance, the copy paper 57 is separated from the photoreceptor 61 by the separating claw 62, and the copy paper 67 is guided to the fixing guide 63, where the toner image on the copy paper 67 is formed by the fixing device 64. has been established,
The paper is discharged onto a paper discharge tray 66. As the photoconductor 61 further advances, the residual toner after the transfer is removed by a cleaning device 66 having a cleaning blade 66a, and the residual charge on the photoconductor 61 is eliminated by a discharge lamp 67, thereby completing the copying process.

点があった。With the configuration of the electrophotographic copying apparatus as described above, it is necessary to fuse and connect the ends of the photoreceptor sheet to form an endless belt. If the circumferential length of the belt-shaped photoreceptor is not uniform, it will meander and unravel during running, and flash will always occur at the fusion splice during each process such as charging, exposure, development, and transfer. Therefore, during cleaning, the blade and the cleaning blade violently rub against each other, resulting in damage to the cleaning blade, resulting in poor cleaning of the photoreceptor. Since the housing and photoreceptor deteriorate due to wear and the like, the photoreceptor must be replaced every time a certain number of sheets are used, resulting in frequent maintenance and inspections. Furthermore, since the photoreceptor is shaped like an endless belt, it is difficult to handle. Since the photoreceptor is in the form of an endless belt, it has drawbacks such as being difficult to handle during maintenance and inspection.

A developing roll is disposed to face the developing sleeve of the developing device, and when the photoreceptor sheet passes between the developing sleeve and the developing roll, the developing sleeve and the photoreceptor sheet are separated by the developing roll. The method is configured to perform development while controlling the gap, and when the photoreceptor sheet deteriorates and reaches its usable limit, the photoreceptor sheet is ejected and a new photoreceptor sheet is taken out from the photoreceptor power center and used. With this configuration, there is no need to fusion-splice the ends of the photoreceptor sheet to form an endless belt-like photoreceptor, so that it is possible to remove the burr at the connection part, and the cleaning blade does not become damaged. The life of the blade can be extended, and high-quality copied images can be stably obtained without meandering of the photoreceptor. A plurality of shredded photoconductors are stored in the photoconductor storage unit 7), and new photoconductors can be automatically replaced after a certain number of used photoconductors 1a, thereby reducing the number of maintenance inspections.

An electrostatic latent image is formed on a sheet, and a developing roll is disposed to face a developing sleeve of a developing device, and when the photoreceptor sheet passes between the developing sleeve l and the developing roll, the gap between them is Developing is performed by controlling the gap between the developing sleeve and the photoreceptor sheet using a developing roll, and the photoreceptor sheet is ejected when the photoreceptor sheet deteriorates and reaches its usable limit. Since a new photoreceptor sheet is taken out from the photoreceptor cassette and used, there is no need to fusion-splice the ends of the photoreceptor sheet to form an endless belt-like photoreceptor, so that the connection part can be easily removed. The dust can be removed, the cleaning blade will not be damaged, the life of the blade will be extended, and the meandering of the photoreceptor will not occur, making it possible to stably obtain high-quality copied images.
